library to clean input to prevent cross site scripting

[jamesd]

We have a javascript that is vulnerable to XSS because the input to
the script is not being checked for strings such as "javascript",
"eval", "script" etc. I have seen some snippets of code here and
there on how to check the strings but I have not yet found a
comprehensive js library that will clean user input of all offending
characters. What complicates it is that phishers can encode characters
to bypass the usual amateurish attempts to clean strings of offending
characters.

Any js libraries or resources out there anywhere?
